KB: How to completely uninstall a free tool

Navigate

In this forum post, “navigate” refers to pasting the panel name or folder name (either relative based on the environment variable, or absolute) into the Windows File Explorer address bar. For example: In Windows Explorer, in the address bar at the very top, press the “Ctrl + V” key combination to paste from the Windows Clipboard the text “Control Panel\Programs\Programs and Features”, “%CommonProgramFiles%” or “C:\Program Files\Common Files”.
